MANUFACTURE OF SHEET-IRON.

Specification of Letters Patent No.

To alt whom it may concern:

Be it known that T, HENRY MGCARTY, of Pitt-sburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Sheet-Iron; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, forming part of this specification, which represents an elevation or face view of the roller employed in my improved process.

The object of my invention is to impart to sheet iron in its manufacture the beautiful mottled appearance presented by imported Russia sheet iron.

The invention consists in the use of planished or hammer dressed rollers, between which the sheets of iron are passed after having been prepared according to the process described in my patent of June 29th 1852. These rollers are arranged similar to 10,047, dated September 27, 1853.

those of a common rolling mill, and reduce the iron but slightly; their surfaces, which present the appearance seen in the drawing giving the sheet passed through them the glossy mottled appearance desired.

I do not claim the use of rollers generally, but

What I do claim as my invention and desire to secure by Letters Patent, is-

Tmparting to the surface of sheet iron the peculiar mottled appearance of Russia sheet iron by passing the sheet between a pair of planished or hammer dressed rollers in the manner substantially as herein fully set forth.

In testimony whereof, I have hereunto signed my name before two subscribing wit-- nesses.
